Given that the random variable X = number of days a student sleeps in during the week, what is the correct notation for the probability that a student will sleep in at least 3 days?
Answer:
X > 3/7Step-by-step explanation:
X > 3/7
We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.

2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight
HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.

12 less than 7 times a number, how do I put this in numbers and symbols and letters
Answer:
7x - 12
Step-by-step explanation:
'12 less' means thats u have to subtract 12 from the next number
'7 times a number' means 7 multiplied by a variable like x, y, or z
you put those two together and get 7x - 12
Answer: 7x-12
Step-by-step explanation:
“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

Answer:
32
63
Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32

cream, including an 8% sales tax.
What was the total cost of all three bowls of ice cream before tax was added?

Answer:
total cost - $3.23 per icecream cone no tax // cost is $9.69 all 3 ice cream cones no tax // solve by multiplying .08 by $3.51. you get .28 // subtract that from $3.51 to solve

You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.
Write an algebraic expression to represent the amount of money left over.
Answer:
75-9d
Step-by-step explanation:
Hello,
The Answer to the question is 75-9d let me explain why,
you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.
You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.
75 - 9d
75 is the total. You need to subtract it by how many books your buying, 9.
The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs
Hope you can understand, I was having some trouble finding a way to explain it so my bad.
Also, I haven't done that in a while so sorry if I'm wrong

How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.

Here is a list of numbers.
32 29 30 37 34 33 31
Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that “37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.
Answer:
a). To find the median from a set of numbers, you need to arrange them from ascending order (smallest to biggest), and then you need to find the number in the middle
b). 32
Step-by-step explanation:
b). Smallest to biggest
29, 30, 31, 32, 33, 34, 37
From the set of numbers given, we can clearly see that 32 is in the middle.
